Locking

What is a door magnet and how does it work?

A door magnet works through electromagnetic forces, securing a given door by creating a magnetic bond between two metal plates. When the system is energised the electromagnet generates a powerful force that holds the door shut, and it remains closed until the door needs to be opened, at which point the system is de-energised to allow the door to open. Magnetically powered doors are therefore a great solution where strong access and entry control are required.  

What's the difference between magnetic locks and traditional deadbolts?

Magnetic locks need continual power to remain engaged, whereas traditional deadbolts are purely mechanical. Magnetic locks have a number of advantages compared to deadbolts in that they can be integrated into security systems to allow them to be a part of the network, and to allow for remote control and instant locking and unlocking. They can in some instances also provide superior security. Mechanical deadbolts on the other hand provide security independent of power. Many facilities choose to use a mixture of access control mechanisms to create a layered security system.

Are magnetic door locks secure?

Yes, magnetic door locks are very secure when they have been installed and maintained correctly. They use electromagnetic force to hold doors firmly closed, making them difficult to force open. The locking mechanism itself cannot be picked like traditional locks, and they integrate well with access control systems for added security.

Can magnetic locks be used in fire safety applications?

Yes, magnetic locks can be used in buildings using fire safety systems. They do however need to be paired with failsafe mechanisms that will release the lock when the fire alarm sounds, to allow building occupants to evacuate safely.

Do magnetic locks work without power?

No, magnetic locks need continuous power in order to work. As soon as power is cut off the electromagnetic force will disappear, which will release the lock and allow the door to open. This is a safety feature in fire situations as mentioned above, however for failsafe security it will be necessary to ensure that a backup power supply or uninterruptible power supply is set up so that the magnetic doors can continue to operate.

Are magnetic locks suitable for external doors?

Magnetic locks can be used on external doors, but installation will need to be undertaken carefully. For example, weather-resistant housing needs to be used to protect the electromagnet from moisture and temperature fluctuations. The metal strike plate must be corrosion-resistant, and the entire system should be installed with proper sealing. For exposed external applications, stainless steel components are recommended to ensure longevity.
